![]() ![]() It is worth underlining how the description of CAT herein provided is to be considered as being merely qualitative, since the formal definition of the transformations would require the usage of an extremely rigorous notation, elsewhere exploited in order to introduce the so-called Music Algebra. The above-mentioned transformations, nothing but particularized inverse chord substitutions, arise from the analisis of a considerable number of traditional jazz compositions, carried out by accurately examining the so-called LEGO Bricks. ![]() The method is primarily based upon the application, carried out by following a specific order, of a set of transformations, named CAT (Cataldo advanced Transformations), by means of which any harmonic progression may be converted into a mere sequence of plagal and perfect cadences.

In this article we briefly introduce an original method, the purpose of which fundamentally lies in providing musicians with a reliable instrument that may effectively assist them in carrying out the chord progressions analisys.

Larger cannula and tubing are recommended for neonatal CPB. Appropriate arterial cannula and arterial tubing should be considered to match the expected flow rate. A small-bore arterial cannula and arterial tubing created high circuit pressure drop and hemodynamic energy loss. Maquet 6Fr arterial cannula had a greater pressure drop than the DLP 6Fr. Compared with the others, the RMI 8Fr arterial cannula had significantly lower pressure drop and energy loss. Hypothermia further increased circuit pressure drop and hemodynamic energy loss. The maximum preoxygenator pressures reached 449.7 ± 1.0 mm Hg (Maquet 6Fr at 400 mL/min), and 395.7 ± 0.4 mm Hg (DLP 8Fr at 600 mL/min) when using 1/8 in ID arterial tubing at 28☌. Higher circuit pressure, circuit pressure drop, and hemodynamic energy loss across the circuit were recorded when using small-bore arterial cannula and small inner diameter arterial tubing in a neonatal CPB circuit. ![]() Flow and pressure data were collected using a custom-based data acquisition system. This chord dictionary includes over a hundred jazz chord forms, from basic 7th chords with all standard tension substitutions and alterations to guide tone chords to triads over bass notes. Trials were conducted at different flow rates (6Fr: 200–400 mL/min 8Fr: 200– 600 mL/min) and temperatures (35 and 28☌).

The circuit was primed using lac-tated Ringer's solution and heparinized packed human red blood cells (hematocrit 30%). The experimental circuits consisted of a Jostra HL-20 roller pump, a Terumo Capiox Baby FX05 oxygenator with integrated arterial filter, an arterial and a venous tubing (1/4, 3/16, or 1/8 in × 150 cm), and an arterial cannula (Medtronic Bio-Medicus 6Fr and 8Fr, Maquet 6Fr and 8Fr, or RMI Edwards 8Fr). The objective of this study was to evaluate five small-bore arterial cannulae (6Fr and 8Fr) in terms of pressure drop and hemodynamic performance in simulated neonatal cardiopulmonary bypass (CPB) circuits. ![]()
